A baby food feeder is a convenient pacifier-style feeding training item for baby food, which can be used simply by putting food into a case called a sack. I threw away the instruction manual, but all parts except the case are dishwasher safe, microwave safe, chemical sterilizer safe, and boil safe. I bought it thinking it would be great for feeding when I couldn't take my hands off of other things! But I never used it. I could only think of putting fruit in it, and I ended up staying with my baby anyway because I was worried. Although I haven't used it, I opened the package and threw away the outer box and instruction manual. I think it would be a convenient item if used properly.
